Water Bed (7th July 2010)

A form of waterbed was invented in the early 1800s by the Scottish
physician Neil Arnott. Dr Arnott's Hydrostatic Bed was devised
to prevent bedsores in invalids, and comprised a bath of water with a
covering of rubber-impregnated canvas, on which lighter bedding was
placed. Arnott did not patent it, permitting anyone to construct a bed
to this design

The bed shapes exactly to the body, thus minimizing pressure, especially
around the joints. Waterbeds remove pressure from the spine allowing the spinal muscles to fully relax, aiding in
the treatment of backache.In
paralytic or movement-impaired people they can reduce the risk of bedsores.
